Outcomes

What you’ll be able to do

  • 01

    Describe a circuit as a loop, and name the four ways one fails

  • 02

    Use a multimeter for voltage, resistance and current with confidence

  • 03

    Perform a voltage drop test and explain why it finds faults nothing else does

  • 04

    Read a wiring diagram well enough to plan where to put the meter

  • 05

    Work safely around vehicle electrics, including what high voltage demands

The lessons

4 modules, 12 lessons

Module 1

Circuits and the Loop

The one idea the whole subject rests on — a circuit is a loop, and almost every fault is a break, a restriction, a shortcut or a dead load.

  2. 02Voltage, Current and Resistance12 minOpen
  3. 03Grounds and Return Paths11 minFree account
Module 2

The Vehicle's Electrical System

Battery and charging, protection by fuses and relays, and why a modern vehicle is a network of modules rather than a bundle of wires.

Module 3

Measuring and Diagnosing

The multimeter, the voltage drop test, and a method for narrowing a fault down instead of replacing parts until it goes away.

The free account only saves your progress and lets you take the exam. No payment, and no card — the certificate is the only thing we ever charge for.

Optional

Certificate of Completion

Pass the final exam and you can add a certificate for $9.90. It carries a unique ID and a public verification page an employer can check without going through you. The course stays free either way.

It states what you completed — not a licence, and not a substitute for the hands-on training and evaluation your employer provides.

Before you start

What this course is.

The classroom half — the part you can finish on your own, before you touch a machine. Your employer does the rest.

Is this a licence?
No. This course covers the classroom portion of training and we issue a Certificate of Completion. Hands-on practice and the workplace evaluation stay with your employer, on the equipment and site you will actually operate.
Do I have to pay?
The course is free — every lesson, every quiz and the final exam. The certificate of completion is $9.90 and entirely optional.
How long does it take?
4 modules and 12 lessons, taken at your own pace. Most people finish in four to six hours across a few sittings. Your place is saved.
What if I fail the exam?
Take it again. Retakes are unlimited and free, and every explanation stays available while you study.
